Connection of the earthing cable

Warning!
welding current cannot flow through hoist chains, crane ropes or
other components that conduct electricity.
connected to the workpiece as close to the welding location as
possible. If the earthing cable is not connected to the workpiece
near to the welding location, the effectiveness of earthing will be
reduced and the risk of electric shock and stray currents will be
increased.

Electrode welding

6.7.1 Electrode welding Fuse Hold function
In this mode of operation, the mains current drain is supervised. If
necessary, the current is reduced to the level necessary to prevent
tripping of the mains fuse. A fast Class B circuit breaker of the type
normally installed in households should be used, as the Fuse Hold
function is designed for use with this type of circuit breaker.
The unit is suitable for welding all the usual types of electrode, with the
maximum current being 140 A for BOOSTER.PRO 170 and 160 A for
BOOSTER.PRO 210. If a higher current is set, the current is limited to
140 A or 160 A.
This current can be used to weld the usual types of electrode up to a
diameter of 3.25 mm.
For the polarity and current settings for individual electrodes, please
refer to the electrode manufacturer's instructions.
6.7.2

Electrode welding with BOOSTER function

If this mode of operation is selected, the mains fuse monitoring function
is automatically de-activated. The maximum welding current output is
150 A for BOOSTER.PRO 170 and 170 A for BOOSTER.PRO 210. If a
higher current is set, it is automatically limited to 150 A or 170 A.
6.7.3

Anti-Stick function

If there is a permanent short circuit during electrode welding, the Anti-
Stick Function is activated after approx. 1.3 s, limiting the current to
approx. 35 A. This prevents the electrode from burning out. The operator
can easily interrupt the short circuit by removing the electrode from the
workpiece.
